การสังเคราะห์สารหน่วงไฟกลุ่มฟอสฟอรัสที่ปราศจากธาตุฮาโลเจนสาหรับใช้งานบนผ้าฝ้าย

The aim of this study was to synthesize a non-halogen phosphate based flame retardant by using chitosan and phosphate compound as substances. The P-N synergistic effect was required in this study. After synthesizing the flame retardant was coated on cotton fabric by dipping then the fabric was tested for flame retardant properties compared to untreated cotton fabric. The three products with N and P in structure were gained by synthesis and confirmed by H-NMR spectroscopy. The time of combustion raised from 14 seconds in untreated cotton to 21 seconds in cotton that treated by product No. 2. Next the mechanical properties of treated cotton fabric are going to measure and the variation of techniques to apply flame retardant on fabric surface is going to test.

This research is aimed to study the characteristics of the good citizen of the students of Rajamangala University of Technology Phra Nakhon and to compare the views on the good citizen characteristics of the students from the above-mentioned university which can be identified by the students’ backgrounds. The research presents the development approaches on the characteristics of the good citizen of the students. The target groups of this research include 1) the executives and 2) the students who registered in the academic year 2012. The research tools consist of the questionnaires and the interviews. The statistics include the frequency percentage mean and standard deviation of T and F value. As for the interviews they were analyzed by making use of the frequency and content analysis. The Result of the study 1. Most students have good citizen characteristics in all aspects as a whole ( = 3.98). As for each aspect it was found out as the followings. For the basic background characteristics the students’ good citizen characteristics on faithfulness were in the maximum average ( = 4.45) whereas the economical characteristics of the students were in the lowest average ( = 3.53). For Knowledge and skill the students’ adaptation in various situations was in the maximum average ( = 4.19) whereas the students’ seeking knowledge and searching for additional learning was in the lowest average ( = 3.66). For Democratic political aspect the students’ appreciation themselves and toward others was in the maximum average ( = 4.25) whereas the students’ demanding or fighting for fairness was in the lowest average ( = 3.82).For Society and culture the students’ respect of the nation religion and the Royal family was in the maximum average ( = 4.48) whereas the students’ participation in the religious activities was in the lowest average ( = 3.70). For Economic aspect the students’ value of faithful occupation was in the maximum average ( = 4.35) whereas the students’ expense books were in the lowest average ( = 3.11). 2. The students’ views on good citizen characteristics of this University classified by the students’ backgrounds can be found out as follows. The students’ different genders were significantly different on the basic background characteristics as well as knowledge and skill at 0.05. The students’ different classes were significantly different on economic aspect at 0.05. The students’ different departments were significantly different on good citizen characteristics as a whole at 0.01. The different parental careers of the students were significantly different on democratic political aspect at 0.05. The different confidence of the students was significantly different on good citizen characteristics as a whole at 0.01. 3. The approaches to develop good citizen characteristics of the students should be implemented as the followings. 1) Revise the curriculum based on student-centered learning aimed to develop good citizen characteristics of the students by balancing the theory and practice to enhance the students’ to be professional and well-rounded. 2). Develop good citizen characteristics of the students by activities. Encourage the students to join the existing activities including the activities outside the university up to the students’ own interest by setting up the importance of joining activities setting the requirement of hours numbers of activities classes and types of activities students have to accomplish.

The objectives of this research are ; 1) To study the dietary behavior of patients with Non-Insulin Dependent Diabetic Mellitus (NIDDM) DonToom Hospital NakornPathom Province; 2) To study the environmental factors on knowledge about nutrition and health self care of patients with NIDDM; 3) To study the relationship between dietary behavior and environmental factors nutritional knowledge and self care factors of patients with NIDDM. Questionnaires were used to collect data Data analysis using the number percentage mean standard deviation and Pearson Correlation (r). The results showed that the majority are female between 56-60 years of age married highest education level: completed primary school agricultural occupation monthly income was 5001-10000 Bahts and the majority lived with husband wife and children. The overall environmental factor affected dietary behavior of patients with diabetes at a high level. The nutritional factor affected dietary behavior of patients with diabetes at the highest level. The self care factor affected their dietary behavior at a moderate level. Study of relationship between dietary behavior personal and environmental factor nutritional factor. and self-care factor have relationship at the statistical significance of 0.05.

Soil Respiration of Natural Forest, Forest Plantation and Agricutural Incubated Soils
Soil Respiration of Natural Forest, Forest Plantation and Agricutural Incubated Soils

Recently scientists have focused attention on soil as a major source and sink for atmospheric CO2. Three replications of two-depth soils from eleven different ecosystem types from Sakaerat Environmental Research Station (SERS) Sakaerat Silvicultural Research Station (SSRS) and Suranaree University of Technology (SUT) Nakhon Ratchasima were collected during the first week of March 2010. The soils were then incubated at 25°C for three days and measured their respiration rates. The highest soil respiration rate was found in sunflower with 0.823 μmol CO2 g-1 h-1 while the lowest was found in eucalyptus plantation in SUT with 0.005 μmol CO2 g-1 h-1. Additionally between two natural forests at SERS the respiration rate of dry evergreen forest was higher than in dry dipterocarp forest with the value of 0.037 and 0.016 μmol CO2 g-1 h-1 respectively. Whereas the soil respiration rate at SSRS forests was highest in the eucalyptus plantation (0.048 μmol CO2 g-1 h-1) and lowest in acacia plantation (0.027 μmol CO2 g-1 h-1). The overall respiration rate was higher for soils from 0-5 cm than 5-15 cm but not statistically significant difference. Soil water content and pH were positively significant related with soil respiration (p<0.01). Soil carbon however was also positively significant related with soil respiration but in lesser degree (p<0.05). Therefore soil water content and pH should be major driving forces for soil respiration.
